Exa Python SDK

exa-py is the official Python SDK for Exa (formerly Metaphor), a neural search engine that indexes the web as embeddings instead of keywords, designed specifically for AI agents and RAG. The SDK wraps every endpoint — neural search with multiple types (auto, neural, deep variants), page contents extraction, find-similar, cited LLM answers, streaming search, and async deep-research tasks. Exa is backed by Lightspeed, NVIDIA's NVentures, and Y Combinator ($22M total raised, TechCrunch July 2024) and powers search in tools like Cursor.

```bash

pip install exa-py

```

```python

from exa_py import Exa

exa = Exa() # reads EXA_API_KEY from environment

# or: exa = Exa(api_key="your-api-key")

result = exa.search(

"blog post about artificial intelligence",

type="auto",

contents={"highlights": True},

)

for r in result.results:

print(r.url, r.highlights)

```
